SECURITY ARCHITECTURE AND MECHANISM TO ACCESS AND USE SECURITY COMPONENTS IN AN OPERATING SYSTEM

摘要

A security architecture is provided for accessing security components associated with an operating system. The security architecture is generally comprised of: a policy tree storing a plurality of security policies, where each security policy is define as at least one system call which correlates to a security operation and a corresponding security component for executing the security operation; and a policy manager adapted to intercept system calls from the operating system and operable to determine an applicable response based on the policy tree. The policy tree and the policy manager reside in a protected memory space of the execution environment.
